Abstract: A bonded sleeve connection was developed for joining tubular glass fiber–reinforced polymer (GFRP) beams and columns. It utilizes a sleeve connector made by welding a steel tube to a steel endplate. The steel tube is then ...

Abstract: pectral polarimetry for weather radar capitalizes on both Doppler and polarimetric measurements to reveal polarimetric variables as a function of radial velocity through spectral analysis. For example, spectral differential ...

Abstract: Metro lines buried in soft soil in coastal regions will inevitably suffer long-term uneven deformation during operation. In this study, the long-term deformation characteristics of metro lines in Shanghai soft deposits are ...

Abstract: The problem of parameter estimation of permanent-magnet synchronous machines (PMSMs) can be formulated as a nonlinear optimization problem. To obtain accurate machine parameters, it is necessary to develop easily applicable ...

Abstract: The safety of operational tunnels impacted by nearby deep excavations has led to growing interest in the field of practical civil engineering. Many researchers have studied the performance of shield tunnels during adjacent ...

Abstract: Deep excavations conducted close to tunnels will cause an adverse impact on tunnels, and countermeasures must be taken during the excavation to ensure the safety of the tunnels. However, the effectiveness of measures to ...
